   Summary

   Somewhat Smallville reference, Clark Kent and Lex Luthor were friends because of Clark saving him. They get older and start to be enemies. They had a past of being lovers for a split second but then Lex changed and they split apart and barely spoke for years. Now Clark Kent is hiding his identity as Superman, partly living with his friend/co worker Lois Lane. Meanwhile, Lex Luthor, already knowing Superman’s identity, his former lover, friend, everything, is hiding a secret of his own. Two secrets to be exact. Two 13 year old secrets.

   Lex and Superman are obsessing over each other, knowing exactly who one another is. The two secrets, are obviously secrets. But a little mishap and Clark finds out about those secrets..

   Anyways enjoy?
